pwrs.core.margcost.margcost(gencost, Pg)[source]#

Evaluate marginal generator production costs.

Mirrors MATPOWER’s margcost helper by evaluating the slope of either piecewise linear or polynomial generator cost models at the supplied output levels.

Parameters:

  • gencost (array_like) – Generator cost matrix.

  • Pg (array_like) – Generator output values at which to evaluate marginal cost.

  • nargout (int, optional) – MATLAB compatibility flag.

Returns:

Marginal costs with the same shape as Pg.

Return type:

numpy.ndarray or float
